Harley Quinn (Starling City's Newest Hero)

"'Hulkie!'"— Harley nicknaming Hulk

Harleen Quinzel, also known as Harley Quinn, is a supervillain that appears in the Hulk/Arrow crossover, "Starling City's Newest Hero".

When Hulk is forcibly recruited by Amanda Waller and Rick Flagg to help the Suicide Squad combat the Enchantress, he joins out of boredom. As soon as Hulk arrives at the Midway City Airport, Harley immediately starts to tease and flirt with him, affectionately nicknaming him, "Hulkie".

After defeating the Enchantress, Hulk and Harley leave the team entirely and spend some time in an old safe house that Harley used when she worked with the Joker some years back. Upon turning back into Bruce Banner, Harley strips naked, easily seduces Bruce, and has sex with him, both unaware that Flechette is watching them...
